在实验室对采煤机截割煤岩过程进行了模拟实验,并对截割过程进行了散斑测试,发现截齿截割中存在局部化变形的规律,这一实验结果对认识煤岩截割机理具有重要意义。
In the laboratory, the experiment of shearer coal cutting was carried out, and the speckle test of the cutting process was carried out. The law of localized deformation in the cutting of cutting teeth was found. Cutting mechanism is of great significance.
